Narrative:

On departure from bct, we were cleared for takeoff. I was the captain and PF. I confirmed with the copilot that our clearance was runway heading, 2000 ft with a turn to 360 degrees after takeoff. He said yes. After takeoff, I turned to a 360 degree heading (takeoff was runway 5) and we were told to contact palm beach approach. Upon initial call-up, the copilot neglected to state our heading. Next call from approach, we were given a higher altitude and the copilot stated our heading of 360 degrees. Approach said we were supposed to be runway heading 050 degrees. Copilot just sat there looking dumbfounded. I took over the radios and said we had been assigned 360 degrees. The controller said 'that'd be ok, stay on the 360 degree heading.' when he (the controller) handed us off to the next frequency, he apologized for forgetting the 360 degree heading -- no problems. I thanked him, thinking no problems. At cruise, I queried the copilot, trying to figure out where the communication problem came in as we had a couple of days left on this trip to fly together. He made a statement which, at the time, didn't quite make sense, but later, after the flight, I got to think about it. Bct has no departure procedure, but it does stress noise abatement procedures. The copilot had given me the noise abatement procedure turn, not the ATC clearance, when I asked him to confirm takeoff clearance. For some reason, he assumed this was mandatory.

Title: A BE40 CREW, DEPARTING BCT, FOLLOWED THE NOISE ABATEMENT PROC INSTEAD OF MAINTAINING RWY HDG, AS CLRED.

Narrative: ON DEP FROM BCT, WE WERE CLRED FOR TKOF. I WAS THE CAPT AND PF. I CONFIRMED WITH THE COPLT THAT OUR CLRNC WAS RWY HDG, 2000 FT WITH A TURN TO 360 DEGS AFTER TKOF. HE SAID YES. AFTER TKOF, I TURNED TO A 360 DEG HDG (TKOF WAS RWY 5) AND WE WERE TOLD TO CONTACT PALM BEACH APCH. UPON INITIAL CALL-UP, THE COPLT NEGLECTED TO STATE OUR HDG. NEXT CALL FROM APCH, WE WERE GIVEN A HIGHER ALT AND THE COPLT STATED OUR HDG OF 360 DEGS. APCH SAID WE WERE SUPPOSED TO BE RWY HDG 050 DEGS. COPLT JUST SAT THERE LOOKING DUMBFOUNDED. I TOOK OVER THE RADIOS AND SAID WE HAD BEEN ASSIGNED 360 DEGS. THE CTLR SAID 'THAT'D BE OK, STAY ON THE 360 DEG HDG.' WHEN HE (THE CTLR) HANDED US OFF TO THE NEXT FREQ, HE APOLOGIZED FOR FORGETTING THE 360 DEG HDG -- NO PROBS. I THANKED HIM, THINKING NO PROBS. AT CRUISE, I QUERIED THE COPLT, TRYING TO FIGURE OUT WHERE THE COM PROB CAME IN AS WE HAD A COUPLE OF DAYS LEFT ON THIS TRIP TO FLY TOGETHER. HE MADE A STATEMENT WHICH, AT THE TIME, DIDN'T QUITE MAKE SENSE, BUT LATER, AFTER THE FLT, I GOT TO THINK ABOUT IT. BCT HAS NO DEP PROC, BUT IT DOES STRESS NOISE ABATEMENT PROCS. THE COPLT HAD GIVEN ME THE NOISE ABATEMENT PROC TURN, NOT THE ATC CLRNC, WHEN I ASKED HIM TO CONFIRM TKOF CLRNC. FOR SOME REASON, HE ASSUMED THIS WAS MANDATORY.
